Two staff sergeants will be court-martialed for their involvement in an incident that included U.S. Marines urinating on dead Taliban fighters and posing for photographs with the corpses, the Marine Corps announced Monday.

Staff Sgt. Joseph W. Chamblin and Staff Sgt. Edward W. Deptola were charged for the incident, which occurred in Helmand Province, Afghanistan, in late July 2011, a news release from the Marine Corp stated. The incident did not come to light publicly until this past January when a 39-second video showing the incident was posted on several websites, including YouTube.
